Working under harsh Antarctic conditions, an international team of scientists, engineers and technicians has set in place the first critical elements of a massive neutrino telescope at the South Pole. The successful deployment - in a 1.5 mile-deep hole drilled into the Antarctic ice - of a string of 60 optical detectors designed to sample phantom-like high-energy particles from deep space represents a key first step in the construction of the $272 million telescope known as IceCube.
